To calculate three quarters (3/4) taken away from 2.5, you first need to convert 2.5 to a fraction, which is 2.5 = 5/2. Next, find three quarters of 5/2 by multiplying 5/2 by 3/4, which equals 15/8. Finally, subtract 15/8 from 5/2 to get the result, which is 5/8.
Well, isn't that a happy little math problem! If we have three quarters, which is the same as 0.75, and we take away 2.5, we simply subtract 2.5 from 0.75. So, 0.75 - 2.5 equals -1.75. Remember, there are no mistakes in math, just happy little accidents!
Well, darling, three quarters take away 2.5 is 0.25. So, if you had a dollar (which is four quarters) and you took away 2.5, you'd be left with a shiny quarter. Math can be a real hoot, can't it?
